Code Review: Redesign Home Screen Again

Small, focused PR. Adds the QUAN logo to the balance display and refines transaction item colors. Clean changes.

DRY Concerns

1. Three color-deriving methods in TxItemData — labelColor, amountColor, and the existing icon color all follow the same pattern: check isIncoming vs isOutgoing, check isHighlighted, return a color from the theme. The branching logic is similar across all three. Consider a single _resolveColor({required Color incomingHighlight, required Color incoming, required Color outgoingHighlight, required Color outgoing, required Color fallback}) helper to reduce the conditional duplication.

2. _quantusLogoImage built inline in AmountDisplayWithConversion — The SvgPicture.asset('assets/v2/uppercase_q.svg', ...) is currently inline. If the QUAN logo is used anywhere else (and it likely will be in a crypto app), extract a small QuanLogo({double size}) widget or at minimum define the asset path as a constant. This avoids silent breakage if the asset gets renamed/moved.

Architectural Notes

• useQuanLogo boolean flag — Adding a boolean to AmountDisplayWithConversion is fine for now, but if more display variants accumulate (different icons, different prefix/suffix styles), consider an enum or a slot-based approach instead of boolean flags.

• Color rename txItemOutgoingHighlight → txItemOutgoingHighlightBorder — Good semantic precision. The old name was ambiguous about whether it was for text, background, or border.

• No state changes, no new providers — Pure UI refinement. Keeps the blast radius small.

Looks good. Minor DRY items only.
